Title: Video telephone system
Inventor: NAKA YUTAKA
IPC: H04M11/06
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive video telephone system that transmits an identification code that denotes a photographed image and a background image to be synthesized with the photographed image without transmitting a synthesized image resulting from synthesizing the photographed image with a background image stored in advance. SOLUTION: The video telephone system 1 uses a transmission section 14 to transmit an identification code that identifies a photographed image photographed by a camera 11 from a frame image. In the case of reception, the transmitted photographed image is synthesized with the background image identified by the received identification code and a display section 7 displays the synthesized image. That is, since the transmitter side does not transmit the synthesized image between the photographed image and the background image, an image memory to store the synthesized image between the photographed image and the background image is not required and then the cost of the system main body can be reduced.
